lamp housing

LED lights have the characteristics of high efficiency, environmental protection and long life. However, people who often use LED lights will find that due to the high brightness of LEDs, it is easy to turn light energy into heat energy, making LED lights very hot. At this time, if the LED cannot dissipate heat as soon as possible, its life will be greatly reduced.

Many LED manufacturers use aluminum housings for LED lamps. The aluminum casing is easy to dissipate heat, has a beautiful appearance, and is light in weight. Many high-end electronic products use aluminum casings. For example, the company's laptop "Mac Pro" high-end computer series products use an all-aluminum casing, which is easy for the laptop to dissipate heat, so that the computer does not even need to install a fan.

The aluminum casing of the LED can increase the life of the wick and make the LED light look beautiful. However, the aluminum lamp cup is relatively expensive to manufacture, and the production cost is very high, and the lamp cup needs to be processed by a lathe. Therefore, some high-quality and medium-quality LED lights will use aluminum lamp housings.

Another common LED lamp housing is a plastic housing. Due to the low cost of plastic shells, some low-end LED lamps will use plastic shells. However, the plastic shell is not easy to dissipate heat, and when the plastic is heated, it is easy to melt and sublimate to produce harmful gases. Therefore, Europe, North America, and Japan do not use plastic casings. Due to the mass demand for cheap LED lights in some parts of the country, the sales volume of plastic casings is very large in China.

Many LED lamps can replace screw-type incandescent bulbs or compact fluorescent bulbs, from 5-40 watts, low-power incandescent lamps, to 60 watts (only about 7 watts of electricity are required). As of 2010, some lamps can even replace higher wattage bulbs, for example a 13 watt bulb is about as bright as a 100 watt incandescent. (General incandescent light is about 14 to 17 lumens per watt depending on its size and voltage. According to EU standards, a "energy-saving light bulb" equivalent to a 60-watt incandescent lamp requires at least Can output 806 lumens.)

Most LED bulbs are designed to be non-dimmable, but some can be operated with dimmers and have a narrower angle of light. Since 2010, the price of these bulbs has dropped from $30 to $50. LED light bulbs are more energy-efficient than energy-saving light bulbs. If the heat is properly dissipated, the lifespan can be as long as 30,000 hours. Incandescent bulbs generally only have a lifespan of 1,000 hours, and energy-saving bulbs only have about 8,000 hours. Therefore, LED bulbs can be used for about 25 to 30 years, and the luminosity decays very little over time. The Energy Star standard stipulates that after the light bulb is used for 6000 hours, the light loss should be within 10%, and the worst should not exceed 15%. Unlike fluorescent lamps, LED bulbs are mercury-free. LED bulbs are also available in different colors. The higher selling price is offset by lower electricity and maintenance costs.
